Isolate x and solve for x:
Add -2x to both sides of the equation.
Add 3 to both sides of the equation.
Divide both sides by 8 to find your x.

Why do you have to add?

ranga · Answer

We are trying to isolate x to one side.
In   10x-3 = 2x+4  there is x on both sides.  I want to get rid of the 2x on the right side.
So subtract 2x from both sides.  (same as saying add -2x to both sides).

anonymous · Answer

I know that you have to subtract 2x from 2x. But from what number do you subtract 2x from on the left side?

ranga · Answer

From 10x.  You can only subtract "like terms".  10x and 2x are like terms.
